' COTTON GIN.

Application filed May 24,

To all whom it may concern:

Be it knownthat I, HENRY E. WERNER, a citizen of the United States, residing at Houston, in the county of Harris and State of Texas, have invented certain new and useful Improvements in 21 Cotton gin, of which the following is a specification.

This invention relates to new and useful improvements in a cotton gin.

. One object of the invention is to provide a cotton gin of the roller type whereby the lint is stripped from the seed, hy'the combined actio-nof a friction roller co -acting with a stripper bar. 1

Another object is to provide a rollergin equipped with a roller and a co-acting stripper bar and embodying a construction, and means, whereby the seed cotton is held by air suction against the roller ina zone of the roller adjacent the bar to insure the efiicient cooperationof said roller and bar: and the lint is thereby completely stripped from the seed without crushing the seed or injuring the lint. i

A furtherohject resides in the provision of means for the agitation of the seed cotton and seed adjacent said barto prevent the congestion thereof and to insure the rotation ofthe seed so that all'of the lint adhering to the seed will be presented to roller and bar, thusinsuring the complete and uniform removal of all the lint.

A still further feature resides in the provision of means for conveying away the lint after it has been removed from the seed, as well as the seed itself.

Another novel feature embodied in the invention consists in the improved construcwtion and economical arrangement of the end frames and connecting breast provided with a suction conduit terminating in nozzles for removing the lint.

A further improvement lies in the construction ofa ginning roll so formed that the air suction is created diametrically through it, instead of being taken through the end bearings with the result that the journals may be made much smaller thus lessening friction and-rendering'the adjacent parts more accessible .l Vit-h the shove and other objects in View, this invention has particular relation to certain novel features of construction, opera.- tion and arrangement of parts, an example of given this specification and other form of this typeof gin.

of roller employed in this form.

Referring now more particularly to the drawings, wherein like numerals of reference designate similar parts in each of the figures, the numerall designates the base of the supporting framework, and mounted on this base are the legs 2, 2 and 3 connected by suitable webs, all forming the framework. In the form shown in Figures 18 there is, a. surrounding hood 4 arcuate in cross section, whose ends are fastened to the respective legs 2, and enclosed within this hood there is a' fan 5 which is fastened on the shaft 6. This shaft is rotatable in bearings carried by the respective legs 2, 2 and 3 and has a pulley 7 fixed thereon,.through which it is driven.

'Located above said hood are the ginning rollers 8, 8. These rollers are between the legs 2, 2 and have reduced ends forming sleeves 9, 9, which rotate in the bearings 10, 10 formed in the respective legs 2, 2. The sleeves 9 receive the connected nozzle pipes 11, 11 which extend therethrough and which, at their union, are connected to a common suction pipe 12. Each roller 3 is hollow and formed with lengthwise rows of perforations 13. Within each roller the corresponding pipe 11 is formed into a long suction nozzle 14, said nozzles fitting closely against the inner surfaces of the rollers 8 and the contacting end of the nozzle is formed to conform to the contour of the roller wall against which it fits. The nozzle outlet is a long narrow slit 15 on opposite sides of which are the packing elements 16, 16.

The sleeves 9, at one end, are extended beyond their bearings 10 and have the bevel gear wheels 17, 17 fixed thereon, and beyond these there are the intermeshing spur gear wheels 18, 18 also fixed on these ends of the sleeves. One of said sleeves also carries the fixed pulley 19, over which a suitaole belt, (not shown) operates to drive the rollers. These rollers rotate in the directions indicated by the arrows in Figure 7 A stripper bar 20 is arranged approximately tangential to each roller. This bar isblade-like in form, that is, it is formed with a comparatively sharp edge adjacent the roller. Each blade is fastened to the breast 21, which is formed with bearings 22. These bearings work on a bearing rod 23 carried by the legs 2, 2. Bolted upon the upper sides of the breasts 21, are the bearing plates 24 and 25, whose contacting faces have the long coinciding grooves, forming a long bearing 26 square in cross section and mounted upon the plates 25 are the brackets 27, which haveflthe aligned bearings 28, also square 'in cross section. Mounted in these respective bearings 26 and 28 are the finger bars 29 and 30, which are connected at one end by a yoke 31. These finger bars are of a form to conform to the contour of the bearings 26 and 28, in which they are mounted to reciprocate, and they have the fingers 32 and 33 secured thereto and arranged in staggered relation, which project out toward the corresponding rollers above the respective bars 20.

In mesh with the respective bevel gear wheels 17, 17 are the pinions 34, 34, which are fixed on crank shafts 35, 35. These shafts rotate in the bearings 36, 36, which are carried by the adjacent legs 2, 2. The shafts 35 are formed withcranks 37 37, on which one end of the respective connecting rods 38, 38 have bearings and the other ends of these rods are connected to the corresponding yokes 31, 31. As thepinions 17 rotate the finger bars 29 and 30 are rapidly reciproeated.

The seed cotton is delivered to the rollers 8 from a suitable delivery chute (not shown) and falls onto, and is separated by, the defiector 39. Approximately equal quantities of the seed'cotton is thus delivered to the respective rollers. The cotton is carried round by the rollers toward the stripper bars 20. It is to be noted that the nozzles 14 are slightly above, or in advance of said bars so that said cotton will come within the suction zones just before reaching said bars, and the suction will cause the cotton to adhere to rollers and the fiber will pass between the rollers and bars, but the seed will be arrested by said bars. Meanwhile the agitating fingers 32 and 33 are reciprocating to prevent the congestion of the seed cotton, and seed. against said bars, and the seed are thereby constantly turned so that all sides will be presented to the bars to the end that the lint will be entirely stripped therefrom. The freed seed then fall down the seed chutes 40 and into a suitable container or conveyor. A conventional form of screw conveyor, as 41, may be provided, if desired.

The lint passes on around the rollers and into the lint fines 42, 4-2 underneath, which unite into a common flue 43. The flue 43 is equipped with a suitable suction fan 44, by means of which a suction is created through said fines to deliver the cotton to any point desired.

The bars and agitating means are carried, as shown, upon the breasts 21. These may be adjusted to regulate the position of the bars and said agitating means, relative to the rollers, This adjustment is accomplished by means of adjusting bolts 45. 4-5, which pass through the lateral lugs 46, 46, formed on the ends of the breasts 21, and are threaded into the framework.

In the form shown in Figures 9 to 20 inelusive, the type of framework is modified in that the legs 3, 3 are not employed. In this form the rollers consist of the tubular shells 4 7, 47. which have slightly spiralled rows of perforations 48. The shell is fitted aimed forming iii effect a shaft The mandrel has lengthwise grooves 51, slightly spiralled, which register with the corresponding rows of perforations 48. The mandrel has a plurality of diametrical bores 52 connecting "the diametrically opposite grooves, as shown in Figures 17, 18 and .19.

Mounted between the rollers, and above them there is a suction nozzle 53 whose ends are anchored to the framework and leading from one end of which there is the suction pipe '54. This nozzle is of an elongated tubular form andv it fits into a seat 55,, arranged underneath it, preferably formed ofleather or similar material. This ,seat has the lateral wings which fit against the rollers and conform to the contour there- .of. These wings are backed by metallic plates 56 and are held 'yieldingly against said rollers by pressure springs 57, which are seated in the nozzle 53. A vertical partition, plate 58 is bolted to the underside of the nozzle and said leather seat'is clamped between them, and secured to the lower edgeof this partition there is a diaphragm 59, of leather or other similar material, U-shaped in cross section and whose edges are turned up between the rollers, asshown inFigure 19.- These leathers enclose between them a long chamber 60, whichis separated, as shown in saidfigure, into two lengthwise compartments and the nozzlehas a plurality of ports 61 leading from said chamber. The partition 58 has notches 62 in its upper edge which register with said ports and permit air to be drawn from. either of said compartments through said nozzle. By this construction suction will be created through the bores 52, successively, as therollers rotate and bring the bores into communication with the respective compartments of. the chamber 60. When in this position the other ends of said bores will create a suction through the opposite perforations 48 just above the stripper bars to hold the seed cotton closely against the rollers until. it is brought within range of the. stripper bars.

In this form one end of one of the shafts 50 hasthe band wheel 63 fixed thereon and also has the spur gear '64:"which is" in mesh with a corresponding gear 65 fixed on the corresponding end of the other shaft 50. The opposite ends of said shafts have the bevel gears 66, 66, fixed thereon which mesh with the pinions 67, 67, which are fi'Xed onlvcrankshafts 68, 68' and are operatively connected with, and reciprocate, the bars 29 and 30 in the same manner "and for the same purpose hereinbefore set forth. v

in this form of gin the breasts 69,69 are 7 stationary and adjustably mounted on them are the bar plates 70, 70, tothe inner edges of which said bars are secured. The plates and 25 are supported on said b'ar plate -pipe 71 which extends rows.

and carry the finger bar which are slidably mounted, as hereinbefore set forth.

Underneath the 'gin there is an air blast upwardly and branches, formingflues 72, 72, whichlead through the breasts and have the long blast nozzles 73, 73, which discharge blasts of air into the enclosed. chamber 74, underneath the rollers and leading from which there is a discharge conduit 75.. The current of. air catches up the lint by suction and frees it' from the rollers and delivers it outthrough said conduit.

'In Figures 21 to 29 inclusive, the chief modifications of the form shown in Figures 9 to 20, inclusive, consists in the specific construction of the rollers and the agitating means.

1" In this form a rocker shaft 76 is mounted inbearings 77 mounted on the plate 24 and 'slidably mounted in this shaft there is a "reciprocating finger bar 78 which carries the agitating fingers 79. The rockershafts 76 carry, at one end, arms 80, whose free ends have rollers 81 which are successively actuated by cams 82, carried by the inner 'recip'rocated back and forth as hereinbefore stated to agitate'the seed and seed cotton to prevent the congestion thereof adjacent the stripper bars, andalso to assist in separating the seed from the lint.

Twotypes'of rollers are employed'in this form of the gin, indicated, respectively, by

the numerals'83 and 84. The roller 83 cons'ists of a drum hired on the shaft 85. This "drum has a pluralityof lengthwise bores 86 and leading'out from these bores are the respective ports 87 arranged in lengthwise The ends of the bores are closed in anysuitable manner and theopposing bores 'are'connected by one, or more, cross conduits 88, which lead diametrically through the drum, but separate into grooves around the central'shaft, as shown in Figures 25 and'2'6. The roller 84; is constructed practically the same as the type illustrated by theroller 83, the exception being that the cross conduits 88 are connected around the -'shaft"8=5'by means of annular channels 89.
